Abstract

Natural radiative lifetimes in the Ss ns Si/2 and Ss nd D3~2 5~2 (n & 20) sequences of indium have been measured using pulsed laser excitation of an atomic beam. The uv pulses were produced by a YAG-pumped, or alternatively, an excimer-pumped dye-laser system. %'hile the 5-state lifetimes show a normal (n ) behavior, the D sequences are strongly perturbed. The lifetimes of the Ss Sp I' states were found to be Jdependent.

Relativistic all-order calculations ofInIandSnIIatomic properties

“…For 7d j -levels, the measurements from Refs. [8,9,11] gave rather different lifetimes. Our calculations support the shorter times obtained in Ref.…”

“…Results for the 5s 2 6s and 5s 2 nd (n = 5-7) levels in In I were given in [8]. Lifetimes of the 5s 2 ns and 5s 2 nd (n ≤ = 20) states in indium measured using pulsed laser excitation of an atomic beam were reported by Jönsson et al in [9]. Determination of radiative lifetimes of the 5s 2 6p, 5s 2 ns, and 5s 2 nd (n ≤ = 10) levels in In I using a pulsed laser was presented in Refs.…”

Energy Levels and Atomic Lifetimes of Rydberg States in Neutral Indium

“…The intensity of the Rydberg states is small and lifetimes relatively long. Jönsson et al [30] have measured radiative lifetimes of some sequences of indium using pulsed laser excitation of an atomic beam. They used UV pulses produced by a YAG-pumped or excimer-pumped dye--laser system.…”

“…The energy levels and lifetimes in both lower lying and highly excited Rydberg states have great importance in the many areas of the physics. Therefore, our energy levels and lifetimes results obtained from the WBEPM theory have been compared with relativistic many-body perturbation theory (RMBPT) and all-order single-double (SD) method results given by Safronova et al [9], results in NIST [26], the results of Andersen and Sorensen including experimental data [10] and the experimental results of Jönsson et al [30].…”

Radiative Lifetimes of Rydberg States in Neutral Gallium

“…It is important to know the lifetime of highly excited Rydberg atoms, which is a parameter that can be compared to existing theories in the literature. During the last two decades, the most of researchers have studied the transition probabilities, energy levels, oscillator strengths and lifetimes of excited states belonging to gallium being in group-three elements having a ground state configuration of 4s 2 of 4p [1][2][3][4][5]. Especially, Zheng et al have calculated energy values using fit procedure in gallium atom.…”
